[Keriaku]

I don't think this is a spoiler, because it was shown at the beginning of Watangashi, but I'll put it in spoiler tags just in case...

Spoiler for Beginning of Watanagashi:

What I want to know is what Shion does to get Rika to kill herself (the scene (I assume) from this chater that was shown at the beginning of Waanagashi). I think Shion will end up killing, or being the reason Satoko dies, and it will push Rika over the edge or something. Or is has to do with Rika knowning she's going to be killed in the next year.
